' Application filed June 26, (No model.)

To al?, whom t may concern:A

3e it known that I, JOHN LA DOW, a citizen ol the United States,- and residing in the city and county of Albany and State of New York,

bales in the same press by alternate action of' parts; and it consists in the construction, combination, and arrangement of parts hereinafter particularly described and set forth.

The objects of myiinproveinents are to produce a simple duplex press which -will be cheaply constructed, durable', and powerful in its operating parts, and be capable of forming and pressing` vtwo bales simultaneously Vwithout lost motion ortime.

I attain theseobjects by means of the de-v vices and modes ofl construction and arrangement of parts illustrated in the accompanying drawings, in which the same letters of reference indicate like parts throughout the several views.

Referring to the drawings7 Figure l represents a side elevation of my improved press. Fig. 2 is a horizontal view fromabove, or plan view,l with the upper planking of the press removed to show the partition-wall. Fig. 3 is a longitudinal `vertical sectional elevation. Fig. 4 is a. cross-sectional view taken at line No. l in Fig. 8. Fig.v 4: is a detail view, showing the adjustable division-pieces.- Fig. 5 is a cross-sectional view taken atline No. 2 in Fig.l 3. Fig. G is an end view of the discharge end of the press, with doors removed. Fig. 7 is a view of the rear end of the press and doors.

Fig. 9 is a plan View of the toggle-lever mechanism and its- Iadjuncts, andV illustrates the .manner in which one limb of each toggle-lever may have its angle changed in relation to the sweep-lever. Fig. 10 is a plan View of one of the retainingdogs, ou an enlarged scale, illustrating its containing device for holding it in place.

struction and arrangement. Fig. 11 is a'perd spective view of the press.

Referring again to the drawings, A represents the lower, and A the upper, platen-chamber; B, the lower, and Bthe upper, balingchamber. The opposite vertical sides of platen-chambersAA are each provided with feedo enin s a and a made each with dimensions v equal to thatof the other, and through said openings (when unclosed by closing-boards) the material to be pressed will be introduced into the respective platen-ch ambers said openings communicate With. rlwo closing-boards, C, Figs. 5 and 8, are provided for closing feedopenings when required..4 The said closing- Aboards are each made of a width corresponding with the vertical extension of -said feedopenings,` and of a length which will extend itsend portions past vertical girts Z) and b', and have bearing against the inner side surfaces of the same, and is stiffened by cleats c `and provided with a button, c', or other re- Said closing-boards are inserted into place in said feed-openings from the inner side of said platen-chambers, and secured by button c', being turned so as to engage with the frame-worker' the press, as shown. In Fig. 5 the two closing-.boards are shown to close the left-hand side of the press, in which case the material will be fed into the platen-chambers through the right-hand openings, a a', and when it is desirable to feed int'o said. chambers from the lefthand side the said closing-boards will be transferred to the right hand side openings. By means of the said side openings and said interchangeable closing-boards all necessity of shiftingthe press or extra shifting of the hay or straw is avoided, so that the press may be planted between two stacks or two bays and be in convenient situation for introduction of the material to be pressed. The length of the platen-chambers is such that there will be a chamber or space, X, in the chambers between the face of the platens when 'they are lat the end of their compressing-stroke andthe adjacent ends of the baling-chambers', in which space the sections of the bales will be formed before being thrust into the baling-chambers.

Ealing-'chambers BB are situated one above the otheraud separated from each other by IOO partition-wall b, which extends through the full length of the press-box, separating also the platen-chambers A A', as shown in Fig. 3, in this class of press, and leave the sides open and introduce a division-plate in each open side, so as to form duplex openings 1;, Figs. l` and 3, in each side. rlhe duplex openings are shown applied to the vertical sides ofthe baling-chamber; but they may be applied to the horizontal sides of a baling-chamber whether a single chamber be used or two chambers employed side by side in a press. These duplex openings occupy a rear and forward portion of each ofthe opposite]y-disposed sides of the baling-chamber, and are separated by the division-pieces b, as shown. These divisionpieces are made of Stout pieces of wood, which are framed into or are secured to the frame-timbers of the press, and extend vertically across the sides of the balingchambers, and are made with awidth nearly or labout' equal to one-third of the entire length ofsaid chambers, as shown, or may be made movable, as shown in Fig. 5 and they are each ma dc to be in situation relatively offsetting from the vertical plane of the inner side surfaces, ci, of longitudinal timbers B2, as shown in Fig. 4. Secured to the inner side surfaces of these division-pieces b* are ledges ci c, which ledges, with the upper surface, c", ofthe lowermost timbers, B, of each baling-chamber, form shelves for temporarily supporting the wire bands Z while they are being placed around a pressed bale, l.,within the balingchamber. Theseledges cand upper surface, c,will in number be equal to the number of grooves in the platen-heads G G and the rear end grooves ofthe respective baling-chambers. These division-pieces bl with beari 11g-ledges c maybe made movable, so that each two opposite ones may be moved toward and from each other, so as to be set nearer to or farther from the bale, as may be required. I prefer to do this by means of slotted brackets y y, secured to the ends of said pieces, and bolts 1/ 1/, passing through the timbers llt and working in the said slots, as shown in Fig. 4. The frametimbers BZ B2 have portions of their vertical inner side surfaces, ci, made to form, with the horizontal walls bL and If b, resisting-surfaces to the sides of the bale, as illustrated in Fig. 4, and serve to steady the sections of the bale when being compressed together and when moving rearward in their respective balingchambers. rllhe rear or discharge ends of said baling-chambers are each closed by a door, the lower chamber, B, by door D, and the upper chamber, B', by door D. I prefer to hinge the lower door D at the rear end of chamber 'B by loop-hinges c c, attached to a rod, so that platens G G, as shown in Fig. 3. If preferred, the said doors may be hinged from the verti cal sides at the rear ends of the baling-chambers; or they may be detachable from the same 7o and be placed in position by the hand of the operator to close said rear ends. These doors operate as resisting-suriaees, against which the material within the balingchambers is pressed and held after being pressed until the 7 bales have been tied ofi or banded.

Extending horizontally across the rear open ends of the baling-chambers are eccentric locking-bars E, arranged in pairs, one pair facing the rear opening of chamber B and the other 8 pair facing the rear opening of chamber B', as shown. The said loekingbars are shown in Figs. l, 2, and 7, and have their outer crankformed ends, i i, pivoted in the timbers B2, with with one end passed through the vertical rear 5 end girts, ff, while the throws of their middle or eccentric portions, i, are made to be in direction rearward when in normal position, as shown in Figs. l and 2. To one end ofthe lowermost locking-ba r of each pair is fixed an angular lever, F, and the short end of each o' said angular levers is pivoted to a link, j. The link'is pivoted at its opposite end to lever or arm 7:, which is fixed to the uppermost locking-bar of each pair, as shown. By means of said angular levers and their connected links and lever-arms each pair of locking-bars will be made to bear against the outer sides ofthe end boards D D of the respective baling-ehambers, when said angular levers are forced downward, or released from the same when said angular levers are forced upward. Door D is shown to be hinged to the lowermost bar of the lower-pair, and door D to the uppermost bar of the upper pair.

Arranged in the sides of the chamber portion X of each platen-chamber are retainingdogs ss. (Shown by dotted lilies in Figs. l and 2 and by full lines in Fig. l0.) rlhe said dogs have each of their rear ends made of a bent I or rocker form, and are held in place from shifting by bolts s and supported forward of said bolt by spring s, as shown in Fig. l0. Then the material to be pressed is crowded against the inner side surfaces bf said-dogs, I said dogs will yield outward to permit a ready passage of the said material, or a divisionboard, (ifsueh a board is used.) After the passage of said material or division-board, the free end of said dogs will be forced inward by i spring si, and will hold against said material or board to prevent their being moved back.

Vorkiug in the lower platen-ehamber, A, is platen G, and with platen-chamber A is platen C. lhe mechanism operating each said i platen in its platelrcliamber consists of togglelevers H H, arranged one on a plane above the other. The lowerniost one of said toggle. levers is pivoted about central with the lower platen, G, and the uppermost one to the up- I per platen, G, in the same manner. The said two toggle-levers are made each equal to the IOO other, and-have each along'linib,v-H,jpivoted1 at one end'toits platenand its-opp'ositeend pivotcdto the short limb H, and also to connecting-bar H2,'.Which hasl :its forward end'piv-4 oted to sweep-lever lK. VThe short limb- H" of each toggle-lever is-pivoted atene-end to long limb H and connecting-bar H2, and -its opposite end to the fixed vertical shaft I. The said two toggle-levers are arranged so that their long limbs H H will each-.beatan op'- posite angle in relationto that of theother, and their short arms H H are-iiXed in relation to the vertical shaft I, sofas to v beradial therefrom, and also in opposition to each other, The sweep-lever K is also pivotedportion of the same, and rod L to t-he upper.

end portion thereof,as shown. The opposite or forward ends of said rods are connected to sweep-lever K by means of the coupling-boltl l, by which also connecting-bars H2 H2 are pivoted to said sweep-lever. A rod, L2, is con- 'nected at one end to the shaft I and at the other end to some suitable part of the press,

and is designed tol brace the shaft against the stra-into which it may be subjected from the connection of the other parts thereto.

By the above manner ofjconstructing and arranging the toggle-levers H- H, and con-' necting the samewith their respective platens G G andfixedvertical shaft I and connecting-bars H2, I' dispense with the use of a double-crank shaft and also with a cross=head, as heretofore used, and am enabled to employ (as a stationary resisting device) a simple stationary vertical shaft, with which the short limbs of both toggles will be'pivoted, as also the rear end of the sweep-lever. By means of the coupling-bars H2 H2 being each pivoted to the pintle which hinges the short and long arms of the toggle-levers together, the vertical shaft 4is .relieved of torsional strain asV the crowding force on the toggle-levers is exerted more or less endwiseon the long limb of the lever, and also exerted on the outer end of the short limb in a direction best calculated to brace .the same from yielding before the resist-ance which' the toggle-levers must each overcome `when pressing the platens against the material in the respective baling-chambers.

By the above-described form of construction and arrangement of the toggle-levers one with the other and their coacting parts, 4the lines of the limbs of each toggle-lever when straightened out or contracted to their full extent will be prevented from being brought coincident with each other or locking past theirv center ofl pivots forthe reason that the inner side surfaces of the long arm of the contracted togglelever'will have abea'ring' against a side of veriincident withthe line ofthe short limb of said toggle, and-will thereby h'old the sweep-lever would force the straightened limbs ofthe other toggle-lever toA such relative positions one `with the otheras to make their lines coincident. By thesemeans the sweep-'lever is made to be free from rebound or sudden reactive impulse when the animals operating `the same 'are being turned and the sweep 'is being reversedin'its direction of movement.

ticalshaft I, (or the ,sleeveu on the same,) and hold said long limb from passing'to a line cofrom being carried onward vto a point which The manner in which the several parts of my improved baling-press operate is as follows, viz: The feed-openings a a at one side of the press-body will be first closed by closing-boards C, and the animal to operate the press will be'hitched vto the outer end of the sweep-lever K; End-closing doors D D will be moved in Vplace in the rear end of each platen-chamber, and the angular levers F will be eachfthrown to position shown in Fig. l, whenthe eccentric portions of locking-bars E of each pair willbe throwntowa'rd each other,

so as to be in position to have bearing on the rear `side of the end-closing doors D D. When thesweep-lever K is moved in direction of arrow 1 to position of dotted linesK in'Fig. 1, the upper platen, G', will be thrust back to the rear end of itsplaten-chamber, and the lower platen will be drawn forward to the forward end of its chamber, and as the animal is being turned to reverse the direction of movement of sweep K the operator will introduce the hay or other material into the lower platen-chamber through the unclosed side opening a, as indicated by arrow in Fig. 5. When the sweep -lever has been moved by the animal in direction of arrow 2 from position of dotted lines K to that of dotted lines K2 in Fig. `2, the 'upper toggle-lever H H will l IIO in the lower platen-chamber back' into the lower hailing-chamber in a somewhat compacted form, and past the retaining-dogs s. Vhile the animal is being turned for moving the sweep-lever back to position K, the operator will introduce a charge of hay into the upper platen-chamber through the upper feedopening a, in direction of arrow, and as the sweep-lever is being moved in direction of arrow l `and from position of dotted lines K2 to those of K,the lower platen will be drawn forward by the lower toggle-lever, and the upper platen will be thrust back and crowd the charge of hay rearward and into the upper baling-chamber, to be held by the retainingdogs s s of said chambers.

A repetition of.

these operations will be made, charges of hay rows l and 2 until both baling-chambers have been filled with compacted sections of a bale, when a partition-board may be introduced into the respective platen-chambers through their respective feed-openin gs (when the platens are iu situation forward) inthe usual manner, and the operation of introduction of other charges of hay into the platen-chambers will be continued. The sweep-lever will then be drawn to position of dotted lines if, and will force the lower platen back against the several charges in front ofa partition-board in the lower ballingchamber, and also exert a great pressing force on the several sections of the forming baleheld between the rear-end elosinfr door and a partition-board or grooved platen-head, G, if the partition-board is dispensed with. The sweeplever will be held in position K2 until the operator has tied off the bale in the lower balingchamber. rlhe position of the sweep-lever will then be changed to that of K, when the several sections of the forming bale in the upper balingchamber will be compressed between upper door D, and a partitionboard, if used, on grooved platen, when the bale will be tied olf. In tying off the bale formed in the hailing-chamber, the operator will, in a direction indicated by arrow No. 3, insert between the inner side surface of division-piece bL (at one of the sides of the balingchamber) and the outer side surface of baleF tie-bands c c, with the tie-bands supported on ledges c3 and the upper surface, ci, of timbers BL', until some four or more inches of the inserted end portions of the band is made to project past the front edge of division-piece If, when these projecting portions of the band will be turned outward and made to engagein narrow notches 'n l1:, provided in the forward edges of said divisionpiece. (Shown iu Figs. 2 and 8.) The operator will then pass theopposite end portions of the tie-band through the slots in the rear-end closing-doors D (or D) in direction of arrow 4 in Fig. 2, and thence forward in direction of arrow, and between the opposite side division-piece bt, and the bale with the wires supported upon ledges c c c, and thence across the baling-ehamber `in direction of arrow 6, and' through the slots in the follower or division-board l?,until their hooking ends are completely passed through, as indicated and shown by dotted and full lines s z :in Fig. 2, when the two ends of eachof said tie-bands will be connected in the usual manner, when the compressing of the bale is fully completed. Angular levers Fwill be thrown upward, and eccentric locking-bars will be turned open and release doors D D,when the lower one will be thrown down and the upper one up. The sweep-lever will then be operated alternately in direction of arrows l and 2, and charges of hay will be introduced alternately in lower and upper platen-chambers, to be carried back by the alternate movements of the platens and be held by the retainingdogs, and as each charge of material is thrust back the tiedoff bales will be gradually worked backward and out from their respective baling-chambers. As soon as the tied-off bales have been fully delivered, doors D D' will be again closed and secured, when the operation of charging the press with material and the moving of the sweep-lever will be resumed and continued until the other bales are formed and tied off in the manner before described. These several operations being continued, a greater amount of hay may be pressed in a given time than is ordinarily done, and the bales thus formed will be made to be more compact than bales are made which are merely pressed under resistance against another bale, and without the resistance offered by an end-closing board or door. )Vhcn the sweep-lever is operated alternately in direction of arrows Nos. l and 2, said sweeplever will swing on or from vertical shaft l, and at each movement in direction of arrow l will force the upper coupling-bar against the hinged connection ends of the long and short limbs of the uppermost toggle-lever H H', and cause said limbs to gradually straight en out and thrust the upper platen, G', rearward, while at the same time the lower coupling-bar H2 will be made to draw on t-he pivoted ends of the limbs of the lower toggle-le- 9 ver H H', and gradually contract the same until checked by the vertical shaft striking against the inner side of the long limb oi' said lower toggle-lever. rlhis will also check the limbs ofthe upper toggle-lever from being fully straightened out, so that all liability of the limbs of either toggle-lever being brought to act at their centers will be obviated. \Vhenthe sweep-lever is moved in direction of arrow 2, lower coupling-bar H2 will be made to gradually straighten out the lower toggle-lever, and upper coupling bar H gradually contract the upper toggle-lever, and in a like manner the said toggle-levers will be prevented from being brought to act on their centers of motion. Thisprevention by the vertical shaft I of the toggle-levers becoming set past or on thel centers of motion removes all liability of the sweep-lever to rebound and endanger the animal when having the direction of movement IOC of said sweep-lever reversed, and all liability of sudden concussions of the limbs ofthe toggle-levers is wholly removed.

Vhen the press is to be transported from place to place, or to be stored away, the bolts a n will be removed from the sweep-lever at its plates m m, and the sweep-lever (having been previously turned to one side) will be swung on coupling-bolt Z to one side of the body of the press, as indicated by dotted lines in Fig. 2.

By means'of the above-described improvements the duplex press is iliade to be more convenient for feeding the charges of material to the press, as that operation maybe performed from either side, while the pressis standing inthe same position, between two stacks or bays. 4

The operation of tying off the bales is made to be more easy and convenient than when done in a vertical direction through slots arranged so that the ties can be passed through them from the bottom to the top of the baling-chamber, as heretofore practiced in duplex presses.

`Bythe employment of a sweep-lever and the two sets of toggle-levers, which are each opi erated but once at each full vibration of said lever, I am enabled to exert great pressure on each bale, and 'also give ample time (at the time of changing the direction of movement of the sweep-lever) for fee'ding the material to be pressed into the feed-openings alternately, as above'describcd; and by means of bars H2 H2, branching from the sweep-lever and being pivoted to the joints of the toggle-lever as they are abovedescribed as being arranged,

- locking-bars E, 'which will be retained.

In some cases it may be desirable to change the angle of the levers Hand H' ofthe toggle mechanism to a .relatively less angle with each other, for the purpose of lesseningthe length of the throw of the platens and also lessening the length of the movement of sweep-lever K, so that-the press may be operated on a barnfloor or at aside of a building. Iwould, therefore, provide in bars H2 H2, Fig. 9, a series of two or more holes, Z' Z', adapted to l`receive the pin or bolt Z for changing the angle of said lever.
